Summary
Busan Bank (BNK Financial Group)
enterprise finance korea
BUSANBANK-AS-KR is the enterprise autonomous system of Busan Bank, the regional commercial bank serving Busan and South Gyeongsang province and the founding subsidiary of BNK Financial Group.
What it's used for
- Reaching the bank's own public-facing services: internet and mobile banking front ends, the card and payment gateways that acquirers and merchants talk to, corporate mail, and the encrypted links between branches, the data centre and interbank clearing networks.
Notable
The evidence points squarely at enterprise, not provider. RIS sees 2 announced IPv4 prefixes, 512 addresses in total, no IPv6, and 2 observed neighbours. Two upstreams and half a /23 of space is a dual-homed corporate edge: the bank runs its own ASN so its public addresses survive changing carriers, and buys transit from two of them so no single ISP failure closes online banking. A network that resold connectivity would show a peer count in the hundreds; there is nothing wholesale about two.
The two prefixes come from different parents (203.239.60.0/24 and 119.195.116.0/24) — an older KRNIC-era assignment alongside a newer one — which is the normal accretion pattern for a long-lived Korean institution rather than any sign of address trading. Both are announced by the bank itself.
Interesting
Busan Bank's ASN was registered in the same run as several other Korean financial institutions; Kiwoom Securities sits two numbers earlier at AS10192 and Kookmin Bank at AS10196. The address footprint is small because retail banking traffic terminates on a handful of load balancers, not on customer-facing address pools.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,849 prefixes, as published 2026-10-30. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
